You'll need a TIFF viewer to read documents accessed through the docket sheets. The best one I've found is Wang Imaging for Windows NT & 95:
Windows NT 4.0: Look in Start/Accessories/Imaging.
Windows 95: Wang Imaging for 95 may be bundled with newer copies. Look under Start/Accessories/Imaging. If you need to download it, it's available free of charge at www.microsoft.com/windows95/info/wang.htm.
